He's kind of an interesting case. While I consider the whole samurai and ninja stuff as stupid as Mr. Bushido in 00, it's still somewhat understandable considering Nielsen is still a kid (at least I think he is), despite being some prodigy physicist. What makes him interesting is that he's not so much into Gundam and the fights as he is interesting in the plasvky particles. He's just so fricking good he could create a highly competitive model and fight with it despite his real interest being elsewhere. He's a much better man than Meijin, who's nothing but a mannequin for the company running the games but still acts like he's the real thing. Meijin's kind of pitiful compared to everybody else, for whom it's a sport and hobby (Iori, Reiji, Mao mostly, Fellini, etc), an object for scientific study (Samurai boy), or simply a job (Aila).
But yeah, it should be an interesting fight. Though I'm repeating myself, but I hope the Aila+Fellini fight will also get some screen time. Above all, I want Iori & Reiji to finally watch a single fight of Aila's, so that they could plan some bloody tactics. It would be their last chance before they face her themselves.
